Summary

This study found that nerve conduction velocity and electromyography (EMG) tests show abnormal results in most patients with venous insufficiency syndrome (VIS). These noninvasive tests may help diagnose and monitor VIS, a condition often marked by swelling and high venous pressure.

Area of Science:

  • Vascular Medicine
  • Neurology

Background:

  • Venous insufficiency syndrome (VIS) is a clinical condition characterized by swelling and high venous pressure.
  • Diagnostic confirmation often involves invasive procedures like venography.

Purpose of the Study:

  • To evaluate the utility of electrophysiological tests in diagnosing and monitoring venous insufficiency syndrome (VIS).
  • To correlate clinical findings and diagnostic test results in patients with suspected VIS.

Main Methods:

  • Studied 23 patients with suspected VIS.
  • Utilized venous pressure measurements, muscle biopsy, venography, electromyography (EMG), and nerve conduction velocity (NCV) studies.
  • Correlated clinical symptoms (swelling, muscle atrophy) with diagnostic findings.

Main Results:

  • Swelling and high ambulatory venous pressure were key clinical indicators, correlating with venography findings.
  • Muscle atrophy was observed in 18 out of 23 patients.
  • Abnormal EMG and NCV findings were present in 20 out of 23 patients.

Conclusions:

  • Electromyography (EMG) and nerve conduction velocity (NCV) studies demonstrated high sensitivity for detecting abnormalities in patients with VIS.
  • These electrophysiological tests offer a potential noninvasive approach for the diagnosis and follow-up of venous insufficiency syndrome.
  • NCV and EMG may serve as valuable adjuncts to traditional diagnostic methods for VIS.
